Abstract

We report the preparation and use of an inexpensive readily prepared optically active 1, 3- disubstituted allene that may be utilized for enantioselective intramolecular allene/enone photocycloadditions. In addition, we describe novel substrates for intramolecular [2+ 2] photocycloadditions which substantially expand the scope of the process to include amino- and thio-tethered allene/enones.
